End to end storm integration tests

Running tests end-to-end

Assumption: A single version of storm binary zip such as storm-dist/binary/target/apache-storm-2.0.0-SNAPSHOT.zip is present The following command will bring up a vagrant cluster.

cd integration-test/config
vagrant up

This automatically will run integration-test/run-it.sh. This brings up a vagrant machine, with storm and zookeeper daemons. And runs all the tests against it.

Running tests for development & debugging

vagrant up command is steup as a complete auto-pilot. Following describes how we can run individual tests against this vagrant cluster or any other cluster.

Configs for running

The supplied configuration will run tests against vagrant setup. However, it can be changed to use a different cluster. Change integration-test/src/test/resources/storm.yaml as necessary.

Running all tests manually

To run all tests:

mvn clean package -DskipTests && mvn test

To run a single test:

mvn clean package -DskipTests && mvn test -Dtest=SlidingWindowCountTest

Running tests from IDE

You might have to enable intellij profile to make your IDE happy. Make sure that the following is run before tests are launched.

mvn package -DskipTests

Running tests with custom storm version

You can supply custom storm version using -Dstorm.version=<storm-version> property to all the maven commands.

mvn clean package -DskipTests -Dstorm.version=<storm-version>
mvn test -Dtest=DemoTest -Dstorm.version=<storm-version>

To find version of the storm that you are running run storm version command.
